iball whom it may concern:

Be it known that I, MORRIS J. HOFFMAN, a citizen of the United States, and a resident of Chicago, county of Cook, and State of Illinois, have invented certain new and useful Improvements in Machines for Bewinding Woven Fabrics, of which the following is declared to be a full, clear, and exact description.

This invention relates to machines for rewinding woven fabric and it has been designed particularly for use in doubling and reminding linings into bolts. In cutting linings, it has been the custom to out each part of the garment lining in duplicate, and in order to accomplish this in a fairly economical manner, it has been customary heretofore to unwind the bolt of lining, double the lining upon itself, and rewind it upon the board upon which it was previously wound. This operation of doubling and rewinding has heretofore been done by hand, and the present machine has been designed to accomplish this task by means of mechanism whereby t e work may be lightened and whereby the time required for doubling and rewinding the lining is reduced very materially. The invention, therefore, consists in a machine having means whereby one-half of the lining may be unwound from the bolt, and thereafter the lining doubled upon itself at the middle, and the two halves rewound upon a board. The invention further consists in the several novel features of construction, arrangement, and combination of parts hereinafter fully described, and particularly defined in the appended claims.

The invention is clearly illustrated in the drawings, accompanying the specifications, in which Figure 1., is an end elevation of a machine embodying a simple form of the present invention; Fig. 2, is a front elevation, looking in the direction of the arrow 2, in 1; Fig. 3, is a detail vertical cross section taken on the line 3-3 of ig. 2; Fig. 1, is a detail end elevation of certain gearing, looking in the direction'of the arrow 4, in Fig. 2; Fig. 5, is a perspective view of a certain. board carrying head; Fig. 6, is a detail longitudinal section taken on the line 66 of Fig. 2; Fig. 7, is a plan, partly broken away, of a certain gage and associated mechanismyFig. 8, isa front elevation of the partsseen in F ig. 7 ;Fig. 9, is a detail cross ,sec itiontakencn the line 9-9of F ig. 7 i; Fig. 10,i's a perspective view of a certain bolt supporting head, and Fig. 11, is a perspective view of a rod securing plate used in connection with said head.

Referring to said drawings, which illustrate a simple embodiment of the present invention, l2, l2, designate the end frame members, which may be of any suitable substantial construction, and said end frame members are spaced apart to receive certain -members of the winding and rewinding devices. Joi irnaled upon stud shafts 13, se cured to the end members, are two bolt supporting heads, 1%, which are adapted to support a bolt of cloth or lining during the unwinding and .rewinding process. Each of said heads 14, has sockets 15, one at each end, for receiving the ends of rods 16. Means are provided whereby. the rods may be readily inserted into raid sockets, and whereby they may be positively held therein, and said means is here shown to comprise a plate 16 one for each head, and having portions 16, extending over the sockets 15. Said plate is adapted to be moved lengthwise to uncover said sockets, whereby the rods may be re moved therefrom or inserted thereinto, and it is here shown as formed with a slot 17, extending lengthwise of the plate through which a screw 17*, passes, and is threaded in the hub 18, of the head; when clamped down upon the plate, it secures it in place. By loosening the said screw, 17, the plate may be moved lengthwise to uncover the sockets.

Above the heads 14, are rewinding heads 19, which are rotatively mounted upon short shafts 20, 21, carried by the end frame-memhers 12; the shaft 20, is movable lengthwise in its support, and is springpressed toward theheads 1 1, by a spring 22, (see Fig. 6) one end of which abuts against an end wall of a socket in wh ch thespring is confined, the other end of which abuts a ainst a collar secured upon the shaft 20. The heads, 19, are formed with hubs 23, secured to said shafts 20, 21, and also formed with elongated socket members 24, having long narrow sockets for receiving the ends of the boards, 25. such as are employed in bolts of material. The hubs, 23 ofthe heads 19, are also provided with non-circular, axially disposed sockets, 26, that are adapted to receive thenon-circular ends of a rod 27. In the arrangement shown. the elongated socket members 24, are placed close to the axis of rotation of the headssoas to leave a slight space between the board 25, and the rod 27. i

Above the rewinding heads is a drum 28, which is here shown in the form of four blades, or vanes, projecting radially from a central hub, although this construction is im material to the invention, broadly considered. Said drum is mounted upon a shaft 29, journaled in bearings in the end frame members 12, and at one end of the machine, said drum shaft 29, and the shaft 21, project beyond the end frame member and carry pinions 30, 31, on their ends. Mechanism is provided for alternatively rotating the rewinding heads, 19, and the drum, 29, and said means is shown in the drawings to comprise a gear wheel 32, mounted upon a stud shaft 33, carried by a lever 34, which is pivotally supported between the pinions 30, 31, by a bolt or shaft 35, secured in the end frame member. Said lever 34, has a handle 36, by means of which it may be manipulated, and it is also provided with a pin 37, which is adapted to enter either of the two notches 38, 39, formed in a se mental part 40, of the end frame member, which segmentis concentric with respect to the bolt, 35. This arrangement permits the driving wheel 32, to be meshed with the pinion, 30, or the pinion 31, whereby the operator may drive either pinion and therewith rotate the rewinding heads 19, or the drum 28. A handle 41, is provided on the driving wheel 32, whereby it may beturned by hand.

Mechanism is provided for indicating to the operator when one-half of the cloth or lining has been unwound from the bolt, or rather when the middle of the lining has reached a point, which, if moved back to the place occupied by the rod 27, will bring the middle portion of the lining into coincidence with said rod. A simple form of indicating mechanism will now be described.

Extending between the end frame members 12, and mounted thereon, is a rod, 42, around which is a tube or long roller 43, over which the woven fabric is moved in winding the same upon the drum 28, or in rewinding it on the rewinding device. Secured upon said roller 43, with screws or otherwise, are two collars 44, that may be adjusted along the roller 43, in accordance with the width of the fabric, and said collars act as guides between which the woven fabric travels. Pivotally supported upon the end frame members, is a supporting member, 45, (see Figs. 7 and 8) which is here shown as comprising a long bar 46, which extends between the end frame members. the bar being bent near its ends to provide two short arms 47, that are pivotally mounted upon the end frame members. Journaled upon the arms 47, of said supporting member 45, is a shaft 48, upon which .are mounted two frictionrollers 49, that rest upon the roller 43, or upon the fabricwhich travels thereon. In the operation to bear against the bar for securing said indicator in place thereon. This indicator may be adjusted along the graduated scale, and set at the place where, when the pointer 54, has been moved to a point coincident with the edge 58, of the indicator, the mid dle of the fabric has been brought into such a position that if moved into a line coincident with the rod 27, one-half of the fabric will have been unwound from the bolt and wound to said rod. A table 61, is secured to the end frame members, and is-convenient for laying the bolt thereon.

Said shaft is provided with a screw In the operation of the machine, the open.

ator takes a'bolt of lining or other woven fabric, which in accordance with the com mon and well known practlce has been wound around a thin board a, and thrusts the rods 16, through the center of the bolt, alongside of the board a, uncovers thesockets 15, in the heads 14, places the ends of the rods in said sockets, shifts the plates 16to cover the sockets and thereafter turns down the screws tohold the plates 16, in place. He then brings the fabric, which is illus trated at A, in Fig. 3, over the roller 43 (the carrying member 45,Ihaving been raised 3 i, therefrom) and secures the end of the fabric upon the drum'28. I l/V hen the drum is in the form shown in the drawing, one or more spring clips 60, are clamped over the cloth and over one of the vanes of the drum 28, to 1 z The secure theend of the fabric thereto. carrier 45, is then loweredto bring the rollers 49, to rest upon the roller 43, or rather upon the fabric on the roller. The operator havingofirst learned the length of the cloth of the bolt sets indicator 56, at the proper place on the scale 55, which indicates the point where the pointer 54, will arrive when one-half of the fabric has been unwound.

The lever 34, is then raised to bring the driv- 1 ing gear 32, into mesh with the pinion .30, and the pin 37 moved into the notch 38, of the segment. The driving gear wheel 32. is then rotated in the direction of the arrow thereon in Fig. 4, andthe drum 28, JCOIISQ.

vquently rotated in the direction of the arrow thereon, in Fig. 3. As the fabric passes the rollers 49, the latter are turned by reason of the friction between the fabric and-rollers,

and .the;screw threaded shaft 48,,isi 11313,-

upon rotated inthe direction of the arrow in Fig. 3. Rotation of the shaft 48, causes the nut '51, and pointer 52, to travel along the shaft 48, and bar .46, and when the pointer coincides with the edge 58, of the indicator 56, the operator stops turning the driving wheel because one-half of the fabric has been unwound, and the middle thereof is in a position, which, when moved toward the rod 27, will coincide with it. The operator then takes the rod 27, and places it in front of the fabric A, pushes the fabric back toward the board 25, which is held in the sockets of the socket members 24, of the heads 19, and inserts the rod 27, into the sockets 26, of the heads 19,

thereby holding the fabric between the rod 27 and the board 25. Thereafter, he lowers the lever 3a to its lowermost position, thereby bringing the driving gear wheel 32, into mesh with the pinion 31. Thereupon, he turns the driving wheel in the same direction in which he turned it while unwinding onehalf of the fabric, thereby causing the board '25, to rotate in the direction indicated by the arrow in Fig. 8, and thereby winding upon said board the ends of the fabric carried by the heads 14, and by the drum 28. The operator continues to turnthe wheel until all of the fabric has been unwound from said parts and rewound upon the board 25. It will be understood that in rewinding the fabric upon the board 25, the friction rollers 49, are rotated in a reverse direction to that in which they were rotated in unwinding the first half of the bolt, and the nut 51, and pointer 52, are thereupon returned to their normal position at O on the scale. When the fabric has been'completely rewound upon the board 25, the operator detaches the board and rod 27, from the heads 19, and removes the rod, leaving the board in the bolt.

More or less variation of the exact details of construction is possible without departing rom the spirit of this invention, and I desire, therefore, not to limit myself to the exact form of construction shown and described, but intend in the following claims to point out all of the invention disclosed herein.
